Co-infection with severe influenza and bacterial is well known, but in recent years, more and more studies report that aspergillus have been identified as important pathogens, secondary only to bacteria in severe influenza.

In order to better understand IAA, this review summarizes the available literature on the association of IAA, including epidemiology, diagnosis and treatment.
